Calving probability in the first and second reproductive years of beef heifers that reached the recommended body weight at first breeding season

Revista Brasileira de Zootecnia
The objective was to evaluate factors that influence calving probability in the first and second reproductive years of beef heifers that reached the minimum recommended body weight (BW) in the first breeding season.

Progressive ataxia of Charolais cattle highlights a role of KIF1C in sustainable myelination. [PDF]

PLoS Genetics, 2018
Hereditary spastic paraplegias (HSPs) are clinically and genetically heterogeneous human neurodegenerative diseases. Amongst the identified genetic causes, mutations in genes encoding motor proteins such as kinesins have been involved in various HSP ...

Impact of using Angus in Charolais × Nellore rotational crossbreeding on calf performance [PDF]

Revista Brasileira de Zootecnia
This study aimed to evaluate the effects of incorporating the Angus breed into a rotational crossbreeding system involving the Charolais and Nellore breeds. The experiment included 67 calves born in 2021, which were allocated to four treatments according

Genetic Parameters and Correlations for Dairy Weaning, 200‐, 400‐, and 600‐ Day Weights in Beef and Beef‐On‐Dairy Progeny Tested Calves

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
The expansion of the New Zealand dairy industry has increased the number of lower‐value surplus calves. A value‐add mitigation strategy is integrating them into the beef market. This study investigated the genetic association between growth traits recorded in the Beef + Lamb New Zealand's Dairy‐Beef and the Beef Progeny Test to estimate the genetic ...

The scurs inheritance: new insights from the French Charolais breed

BMC Genetics, 2009
Background Polled animals are valued in cattle industry because the absence of horns has a significant economic impact. However, some cattle are neither polled nor horned but have so-called scurs on their heads, which are corneous growths loosely ...

Heteroskedasticity for weaning weight of Charolais-Zebu crossbred calves

Revista Brasileira de Zootecnia, 2012
The objective of the present study was to analyze models with genetic and/or residual heteroskedasticity for genetic evaluation of the weaning weight of Charolais-Zebu crossbred calves. Weaning weight data from 56,965 crossbred calves were analyzed using

Nutrition Management Strategies for the Adaptation of Cull Beef Heifers to Feedlot

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
Providing diets with high roughage in the first days of confinement is the common way of adapting beef cattle to intensive production. However, it is possible to offer the final finishing diet from the first day of adaptation. Our objective was to compare a traditional adaptation protocol, in which animals received a diet with a higher proportion of ...

Study of Genetic Progress in the Context of Disconnection Between Two Originally Connected Populations

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 24-34, January 2026.
ABSTRACT Genetic progress of breeding programs is highly dependent on the size of reference populations and the relatedness between reference populations and selection candidates. Many reasons can lead a population to split into several subpopulations (sanitary, physiological, political reasons, etc.).

Genetic Heterogeneity of Residual Variance for Foot Score Traits in American Angus Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 68-78, January 2026.
ABSTRACT Foot conformation is one of the main breeding goals in recent beef cattle breeding programs because it directly affects productivity, economic losses, animal welfare and longevity. Genetic heterogeneity of residual variance can be used to improve production uniformity in animal breeding programs because recent studies have shown that residual ...
